Atv parking brake

Abstract

An all terrain vehicle parking brake for after market installation on an ATV, UTV, RUV or MUV that relies on placing the vehicle shift lever in a park position to hold the vehicle on a hill. The parking brake includes a brake handle that is mounted to the vehicle dash board to pivot between brake engaged and disengaged positions, extending and retracting a linkage that connects and disconnects through a straight sleeve, with the linkage connecting to a rod end bearing that connects to a brake pedal arm, depressing the brake pedal when an operator activates the parking brake.

         10 . The parking brake assembly as defined in  claim 1 , wherein when said brake pedal is selectively positioned in said disengaged attitude, said control handle is disposed in linear alignment with said length of said shaft. 
     
     
         11 . The parking brake assembly as defined in  claim 1 , further comprising a first collar engageably disposed along at least a portion of said extended length of said first guide shaft and a second collar engageably disposed along at least a portion of said extended length of said second guide shaft, wherein said first and second collars structurally restrict the slidable movement of said sleeve. 
     
     
         12 . A brake assembly comprising:
 a brake pedal movable between a disengaged attitude and an engaged attitude;   a mounting bracket having a length providing a flat face surface and an opening formed therein;   a linkage assembly disposed in relation to said mounting bracket, said linkage assembly comprising a control handle movable between a first position and a second position;   a shaft comprising a length formed between first and second opposing ends, said first end of said shaft pivotably engaging said linkage assembly and wherein said length of said shaft being disposed perpendicular to said flat face surface and extending through said opening in said mounting bracket;   a first guide shaft comprising an elongated length formed between first and second opposing ends, said first end of said first guide shaft engaging said second end of said shaft and said second opposing end of said guide shaft comprising an abutting surface;   a second guide shaft comprising an elongated length formed between first and second opposing ends, said second end of said second guide shaft comprising an abutting surface;   a rod end bearing having a first end engaging said first end of said second guide shaft and a second opposing pivot end disposed in pivotal engagement with said brake pedal;   a sleeve comprising two opposing open ends and an inner wall surface having a length and a diameter sufficient to house at least a portion of said elongated length of said first guide shaft introduced within said first open end and further disposed in alignment with at least a portion of said elongated length of said second guide shaft introduced within said second open end, said length of said sleeve being less than the combined elongated lengths of said first and second guide shafts, and wherein said sleeve is slidably disposed relative to said elongated lengths of said first and second guide shafts introduced therein;   a first collar engageably disposed along at least a portion of said extended length of said first guide shaft and a second collar engageably disposed along at least a portion of said extended length of said second guide shaft, whereby said first and second collars structurally restrict the slidable movement of said sleeve;   wherein when said control handle is selectively moved into said first position, said abutting surface of said second end of said first guide shaft is disposed in a spaced-apart relationship to said abutting surface of said second end of said second guide shaft within said sleeve, thereby placing said brake pedal in said disengaged attitude; and   wherein when said control handle is selectively moved into said second position, said abutting surface of said second end of said first guide shaft structurally engages said abutting surface of said second end of said second guide shaft within said sleeve, thereby selectively locking said brake pedal in said engaged attitude.
